项目部署一般是两种方式：
一种是打包成 jar 包直接执行，另一种是打包成 war 包放到 Tomcat 服务器下，SpringBoot一般情况下默认为jar包方式。
pom.xml：
< packaging>jar< /packaging> （默认）
< packaging>war< /packaging>
打jar包
选择 File -> Project Structure->Artifacts->Jar->Form modules with dependencies后点ok:
根据 下图内容创建 jar。如图所示，选择项目，入口类等。最后一项 META-INF，默认放到 src\main\java 目录里，如果使用默认值，没有进行其他配置，生成的 jar 有可能不会包含 META-INF 目录，导致运行 jar 出错。最好放在 src\main\resource目录中。点击ok保存。按下图所示配置：
点击ok会出现如图所示信息:
生成jar包
点击idea菜单栏中的build，依次选择：
点Build:
在保存路经中查找所打包的jar包如果存在则说明打包成功。
运行jar包
开始运行jar包，打开cmd进入jar所在的路径，输入java -jar xxx.jar (jar名称) ，点击回车按键。
